4l Claims. (C1,y 12s-ical This invention relates to `visible index cardl systems and `particularly to' marginal `protecting strips for the'cards therein.' r' r In the art it is 'conventional to vprovide va 5visible index card with a marginal protecting strip, "but suchprotecting strips' have had Vone or more lof a number of disadvantages.It is an object of my invention therefore to 'provide a novelcombination of pocket and protecting m strip whichbroadens thel scope ofuse of the system. It is another object of my invention to provide aprotecting strip` which is easily inserted in place and which may easilybe removed if desired.

It is a further object of my invention to provide a marginal protectingstrip of such a nature that a record card may be inserted on either orboth sides of the pocket.` A still further object of my invention is toprovide a protecting strip of such a nature that with record cards inplace on either or both sides 'of the pocket smaller Vcards or slips ofpaper bearing temporary memoranda later to` be transferred to the cards,may be insertedin,saidjmarginal protecting stripfon either side of thecard or pocket and'at any location along the entire bottom thereof.These and other objects of my invention which willbe apparent to oneskilled inthe art upon readingthesespecications, I accomplishby thatcertain construction andarrangement of'parts of which I shall nowdescribe a preferred yembodiment.` Reference is'made to the drawingwhich forms a part hereof,` and in which:

@Figure 10 is` across sectional View similar to Figure 5 but showing amarginal protective strip disengaged from an index card.

Y, fBriey, in the practice of my invention, I provide alcard pocketmember indicated generally at IB, `which may be made from kraft' paperor any conventional ,materiaL This card pocket may be provided with adown-turned upper edge portion I I for mounting it in a card holdergenerally indicatedat fl2. The card holder is con' ventional and willnot be` described in detail `exceptto say that it includes as a hingeelement a strip I3 having outwardly-extending arms I4 and I5, the arm I5having an in-turned end portion lIIS.` As will be seen from Figure 2,the pocket I vismounted in the member I3 with the downturned edgeportion II engaging the members I and|6.@"x At the. loweredge, the`pocket I0 is provided with scoring at I'Ia and the lower edge is turnedup as; at I1. Additional scoring is provided -at I'Ib, the distancebetween the scoring at IIa and I'Ib lbeing `substantially equal to thedepth of the protecting strip I8., The scoring at I'Ib may consistV ofasingle line but is preferably double as shown, and its purpose is toimpart flexibility tothe lowermargin whereby it is less likely to beinjured and whereby any tendency of the pro-L tecting strip to' spreadis avoided, when the lower margin is raised in order to examine a lowercard or pocket inthe flle. j f 'Ihe margin protecting strip indicatedgenerally at I8 in Figurey 1, may be made from any transparent materialsuch as Celluloid; but I prefer to make the samefromcellulose acetate,for the1easonthat cellulose acetate is not highly inflammable likeCelluloid. 'Ihis is of great advantage sinceitcuts down the re hazard.Preferably the cellulose acetate is' treated to give it a dull iinish sothat its surface is not highly reflective, although it remainstransparent. 'I'his is advantageous in that glare and reflection fromthe margin protecting strip are substantially eliminated, which tends tocut down eye fatigue on the part of the user of the system. In acopending application Serial No. 272,187 iiled May 6, 1939, in the nameof Charles Butterfield, there is described a novel process forforming acellulose acetate strip and preferably the strips I8 are made accordingto that process.

The member I8 is generally U-shaped in cross section having a bead I8ain order to provide a spring action in the arms I9 and 20 which are 55inwardly down-turned respectively as indicated at 2l and 22. It will benoted that the portion 22 bears against the arm 20, while the portion 2|is slightly spaced from the arm I9 so as to accept theportion I1 of thepocket. At least one of the arms is'of such extent that it will snuglyengage over the up-turned marginalv portion I1 of the pocket. In theVpresent instance I have indicated the arm I9 as being of suchdimensions. 'I'he down-turned portion 22 is primarily for the purpose ofproviding a smooth finish alongY theV top of the strip and I prefer tomake the arm-20 somewhat longer than the arm I9 so as to provide abetter contact. As shown in Figure 4, thel 15 protecting strip I8 isassembled to the pocket IU by sliding it into .position with thedown-turnedv portion 2I engaging over the up-turned portion Il. In orderto facilitate the assembly, I prefer to cut either or. both ends of themember I1 as at IIc. Thus the lower edge of the pocket and the11p-turned portion I1 are slipped between the arms I9 and 20 in themanner of a knife, and then the member I8 may be longitudinallywithdrawn until the diagonal cut IIc clears the portion 2| whereupon`the 'natural resilience of the pocket causes the member I'I to springoutwardly and engage underltheportion 2I. The stripl may then belongitudinally slid into position.

A record card may be inserted at the top as shown in Figure 2, the.recordV card itself being indicated at 23. It will. be clear thatanother record card could be inserted on the right hand side of thepocket` I0 in the space indicated at 24. The lower portion of the recordcard 23 extends` down along the pocket II)` and behind the arm 20 asseen-in Figure 3'. As shown in Figure 5, a supplementary'slip orcardbearing temporary indi'cia'may be Aslipped in. between the record card23A and the portion 20, as indicated ,am at 25. Similarly as shown inFigure 6, an additional record card 2S may be inserted on the other sideofV the 'pocket I0 andi likewise temporary 'sli-ps or cards may beYinserted as shown at 21. It' will be understood' that if the slips are:45 long enough, the topy vedges thereof may be engaged under the'members I4 and. I5 respectively. Ink Figure 10, I4 have shown thelappearance in cross section of the marginal protective strip before itis attached tothe index' card. Itwill 50 be 'clear 'from this gurehowkthev fact that one armat 2Il`is` longer than the `other arm at I9permits the downturned. portions .27| `and 22 to lie substantially inthe same plane, which. `fact accounts. for the heightened grippingaction g55 achieved according to myinventi'on.

In Figure 9 `l'. have shown. a supplemental slip Illa which may beprovided with; adown-turned top edge I'Ia.. .Such a slip :may .engagelthe. card holder in the same manner as the pocket itself ,60 and willthusbe securelyA heldin place; It can only be removedby sliding it outlaterally.`

It will be clear from the drawing that there is provided an unobstructedspace along the entire lower margin of the pocket and onboth sidesthereof for the reception of any cards or temporary notes which arelater to be transcribed onto the record card proper. All such notes andall indicia on the record card will be visible even below the protectingstrip on account of its transparent character.

In certain cases it may be desirable, for reasons ofV economy orotherwise, to eliminate the pocket I0. It will lbe clear that the recordcard itself may be made to have the form of the pocket I0, having thedown-turned edge II for attachment to the holder I3, and having theupturned lower edge portion Il for the reception of the marginprotecting strip I8. In the claims, therefore, the term card is intendedto include in its scope the term pocket It will be understood thatmodifications will suggest themselvesl to. 'those skilled in the artvand that I therefore do not intend to limit myself otherwise than. aspointed out in the claims which. follow. v v

Havingrnow full described my invention, what I claim as new and desiretoA secure by Letters Patent is: y Y

' l. In combination with anindex card having an up-'turned lower edgeportion, a protecting strip, said strip vbeing generally U-shaped invcross section, onev of the arms of said U :being longer than the other;and said strip `being provided with inwardly down-turned edge portions,said strip engaging over the lower edge of said card and the shorter ofsaidv arms being of such length that its` inwardly down-turned edgeportionts snugly over the up-turnedl edge portion oi said' card, 'and'the llonger of said arms being oflsuch length that the down-turned'vedge portion clears the said shorter arm, said down-turned portions whennot engaged on said 4index card lying substantially in: asingle plane.

2. A. protecting strip -for Visible index cards, said vstrip beinggenerally U-shaped in cross section and having inwardly down-turned edgeportions, one. of the arms." thereof being somewhat l'o'nger than thevother, so that the downturned edge .portion thereof clears the4 otherarm, said down-turned edge portions lying substantially' ina singleplane.

3. A-.protecting strip according to claim. 2. in which lthe curvature.oi the U is enlarged to providefa bead-likeA cong-uration.

4. A protecting strip according to claim 2 in which the connectingportion. between said arms issubStantiall-yonA the arc of a circlehaving a diameter slightly'igreater than the distance between said arms.Y
